Sink base cabinets are made to allow you to install a sink on top of them, so they lack shelves inside to make room for plumbing. This allows them to double as storage for taller cleaning materials and other items if desired. Our Summit Craftman White Single Door Sink Base Cabinets match our Summit Craftman White cabinetry to provide a consistent and seamless look throughout your kitchen. They feature a single drawer above the door. This Single Door Sink Base Cabinet measures 21" wide x 34.5" tall x 24" deep. Check out available customizations such as cabinet depth modification and choice of hinge direction.
